I am building a site with a course content type. Users can only view some of the course details (such as date, location and description) unless they are registered on the course. Once registered their is certain webforms and file downloads related to the course which they can access too.
A company admin user (sponsor) should be able to access specific courses, and if they have access to a course they can invite people (delegates) to register on the course. Basically each individual course is by invite only.
I'm a little confused as to how to build this. I assume Organic Groups, and/or Entity Registration may be the right direction, but I've never actually used either Module. Does anybody have any suggestions on how I can build this? Which Modules should I use and does anybody have any tutorials or references which may help in this specific area?
